Spring Lock Coupling: Connect

NOTE: It is imperative that the sealing surface of the spring lock coupling and O-ring seal be clean and completely free from debris. To prevent contamination, only new PAG oil should be used as an O-ring seal lubricant. Contamination from used PAG oil, residual PAG oil from inside the refrigerant system or a failure to thoroughly clean the fitting sealing surface will interrupt the O-ring seal-to-fitting sealing surface and cause refrigerant system leaks.
